Fn (base.Base.Fn)

val (|>) : 'a -> ( 'a -> 'b ) -> 'b

A "pipe" operator.

val const : 'a -> _ -> 'a

Produces a function that just returns its first argument.

val ignore : _ -> unit

ignore is the same as Caml.ignore. It is useful to have here so that code that rebinds ignore can still refer to Fn.ignore.

val non : ( 'a -> bool ) -> 'a -> bool

Negates a boolean function.

val forever : ( unit -> unit ) -> exn

forever f runs f () until it throws an exception and returns the exception. This function is useful for read_line loops, etc.

val apply_n_times : n:int -> ( 'a -> 'a ) -> 'a -> 'a

apply_n_times ~n f x is the n-fold application of f to x.

val id : 'a -> 'a

The identity function.
